PRESTON O. MORSE, OF NATICK, MASSACHUSETTS, ASSIGNOR TO THE NATIONALCLOTH CUTTER COMPANY, OF

PORTLAND, MAINE.

CLOTH-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 585,279, dated JuneApplication filed March 4, 1896.

To all whom it may concern:

Be it known that LPRESTON O. MORSE,a citizen of the United States,residing at Natick, in the county of Middlesex and State ofMassachusetts, have invented a new and useful Improvement inCloth-Cutters, of which the following is a full, clear,and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature.

The invention relates to the class of clothcutting machines which aremovable over a table or bed upon which the cloth in layers or piles isheld, and its objects are to increase the capacity of such machines inrespect to the number of layers of material cut at one operation, therange of the machine in respect to the kind of goods operated upon, andthe ease and certainty with which it may be guided and operated.

The first two objects are largely obtained by means of the peculiarcutting devices employed and the manner in which they are used. Brieflystated, they consist of a long narrow rest or foot attached to the frameof the machine by a thin vertical arm extending upward from the rear endof the rest or foot, the upper edge of the rest or foot having at itsjuncture with the vertical support a stationary shear cutter or bladeand also a cloth lifting incline extending downward from the lower edgeof this cutter to the forward point of the foot or rest, and whichstationary shear cutter or blade and vertical arm are combined with along, narrow, rapidlyreciprocating cutter of large throw having asharpened lower edge and so shaped, supported, and operated that itsside at its rear lowercorner is held in contact with a straight surfaceof the vertical arm during a large part of its reciprocation and untilits cutting edge is brought into operative relation with the stationaryshear cutter or blade, when the said reciprocating cutting edgecooperates therewith to make a shear cut like the shear cut ofa pair ofscissorsthat is, a out where the cutting edges of the blades have but asingle advancing contact at and with the point of their intersection orcrossing. The reciprocating cutter has a large range of movement inrelation to the li tting and holding foot and lowershear- 29, 1897.Serial No. 581,750. (No modeL) cutter in order that a large numberoflayers, as many as one hundred and fifty to two hundred of some kindsof material, may find room between the lifting-foot and the cutter, Thelifting-foot serves to hold the material lifted from the bed during theoperation of the reciprocating cutter and to maintain it against thethrust and shearing action of the same. The cutting mechanism may besaid to have two cutting actions. The first is that which takes placeduring the greater part of the reciprocation of the cutter, when the cutis largely made by the direct thrust of the cutter into the assembledlayers. The second action is that obtained at the time the reciprocatingcutter begins to act with the stationary shear cutter. or blade incutting the lowermost layers of the material, when the reciprocatingcutter and the stationary shear-cutter act in opposed relation to eachother as shears and cut witha shearing cut, and it is largely owing tothis last action of the cutting mechanism that the capacity and range ofthe machine are increased, as it is very essential that the lowermostlayers always be cut and cut cleanly and accurately, for if they are notso cut the cutting-machine cannot be fed, the partially-severed lowerlayers acting to bar its movement, and of course the harder the materialis to cut the more likely it is to give trouble at the lower layers, andI am informed that the previous cutting-machines of the market have inpart failed to cut a large number of layers and certain kinds of fabricbecause of the inability of their cutting device to sever satisfactorilythese lower layers.

The third object of the invention is ob tained by the employment of thethin long foot or rest of the character specified, which lightly bearson the table or support and is moved beneath the goods with but littlefriction, by a yielding presser-foot which cooperates with the cuttingmechanism, by the use of a guidinghandle located above and in line withthe cutting devices, and by bringing into operative relation with suchhandle means for controlling at the will of the operator and by the handused in guiding the machine the operation of the reciprocating knife, aswell as the lifting of the presser-foot.

The invention also relates to various feabe cut is supported.

tures of organization and construction by which an improved result inrespect to wear, avoidance of friction, and proper balancing of parts toprevent friction are obtained. The machine is suspended in any desirableway to permit of its easy and universal horizontal movements over thetable or bed upon which the layers of material have been placed infollowing thelines of the pattern, which are generally marked inadvance, upon the upper surface of the upper layer. I prefer to employfor this purpose the crane or jointed arms heretofore used withcutting-machines, one feature of my invention, however, relating to aminor improvement in the manner of connecting the outer arm with theinner, whereby an adjustable slight vertical yielding movement ispermitted the cutting-machine.

I will now describe the machine in connection with the drawings thereof,wherein- Figure 1 is a view in side elevation of the cutting-machine,its suspending devices, and the operating-bed upon which the material toFig. 2 is a view in plan of the cutting mechanism, its supportingarms,and its actuating-belts. Fig. 3 is aview in side elevation, enlarged, ofthe cutting mechanism, a detachable portion of the front casing of thefront section being removed to show the structure behind it.

Fig. 9 is a view in left-endelevation thereof. Fig. 10 is a view in left-end elevation, enlarged,representing the relation between the reciprocating cutter or blade withthe foot, shearcutter, and arm. Fig. 11 is a view in front elevation ofthese parts. Fig. 12 is aview in vertical section upon the dotted lineas a: of Fig. 11. Fig. 13 is a view in rear elevation of the partsrepresented in Fig. 11. Fig. 1.4 is a view in horizontal section uponthe dotted line y 1 of Fig. 11 and a plan of the parts below said line.

The machine housing or frame has two principal parts or sections-namely,the rear part or portion A. which supports the drivingshaft, the drivingand driven pulleys, and the device or means connecting the machine withthe outer end of the second arm of its jointed support, and the portionA, which provides a support for the reciprocating knife block or headand which is shaped upon its outer part to provide a handle in line withand above the cutting devices-by which the machine is held and guided.There is interposed between these two sections the connections betweenthe main shaft and the reciprocating head or block. This constructionnot only provides a desirable location for the reciprocating head orblock and a satisfactory disposition and balancing of the weight of themachine in respect to the arm and in respect to the handle, but also ahandle which is very desirably located for the purpose of the easy andcorrect guidance of the machine, as it brings the operator into suchrelation therewith that he can readily observe and follow the action ofthe cutter in respect to the line upon which it is cutting.

To understand. the operation of the machine, it should be borne inimindthat the material to be cut rests upon a table or bed and that thecutting-machine is moved by hand,

generally upon lines marked upon the upper surface of the goods ormaterial, and it should also be understood that during such movement ofthe cutting-machine the goods or material are lifted from the bed by theliftingfoot attached to the cutting-machine and which rests lightly uponthe bed.

Any suitable mechanism for holding the cutting-machine and permitting itto be universally moved by the operator in horizontal directions may beused, and I have represented as a desirable means for accomplishing thispurpose the horizontal arm B, which is connected with a vertical support13 by an intermediate horizontal arm B (See Figs. 1 and 2.) The latterarm has a horizontal swinging movement upon an arc of which the supportB is the center. The arm B has a horizontal swinging movement upon theend of the arm B and it is so attached to it that its outer end and thecutting-machine may have a slight vertical movement in relation to thebed 0. The cutting-machine is attached to the end of the arm 13 in amanner to permit it to be turned upon a vertical axis. This way ofsupporting the cutting-machine is designed to provide it with auniversal movement in a horizontal direction upon the bed 0 and to alsosupport it so that it shall bear but lightly upon the bed, and thereforebe readily moved by the operator.

The section A of the housing or frame of the machine supports a verticaldriving-shaft at, having at its upper end the fast pulley (Z and theloose pulley (Z and at its lower end a bevel-gear d ,which meshes withthe bevelgear (1 on the horizontal shaft (1 This bevelgear is connectedby a crank-pin d and connecting bar or link d with a reciprocatingcross-head (1 mounted upon the stationary rods (1 61 supported by thesection A of the housing, and to which cross-head the upper end of thelong narrow blade or cutter E is secured, the blade preferably being soattached to the cross-head as to be vertically adjustable thereon. Theblade or cutter E thus has imparted to it a rapid reciprocating movementof very considerable length. Its lower or cutting edge e is preferablyinclined from its forward corner 0 downwardly and backwardly to thereareorner e and is brought to the face side of the blade and made sharpby the bevel e upon its back side. also, preferably, has the straightvertical rear edge e and the slightly-inclined front edge 6 which, ineffect, causes the cutting section or edge of the blade or cutter to beat its widest part, the corner 6 being slightly in advance of theremainder of the forward edge 6 The blade is also made thinnest at thefront or forward edge e especially toward the lower part of the blade,and this reduction in thickness is made upon the back side of the blade,the face a of the blade being flat. The blade is also bent in its shankor upper end or held to throw its lowest section slightly forward ortoward the arm F, carrying the foot F, in order that it may always, uponthe face adjacent to the rear corner 6 maintain a contact with the rearface f of the said arm during its entire reciprocation and until itreaches the stationary shear-cutter F The said shear-cutter F extendsfrom the cornerf of the foot to the point f Its cutting edge is turnedlaterally from its rear end inward to form a slight angle with the backface of the arm F and the front face of the reciprocating blade at itscutting edge e. It is sharpened by a beveled surface upon its outer sideand by an undercut back face, the slight hollow f being used for thepurpose of forming this undercut edge. In other words, this cuttingsection of the foot is given the characteristics of a shear andcooperates, in connection with the reciprocating cutter, to make ashearing cut.

The foot has a forward extension f, the upper edge f of which isinclined downward to the point f and a lower edge f ,which is straightand narrow and is adapted to bear and ride lightly upon the surface ofthe bed.

The arm F has at its upper end a horizontal section f in the nature of across-bar, which is integral with the rest of the arm and acts inconnection with the fasteningscrewsf to secure the foot to the frame orhousing. This bar also spans the opening (Z in which the cutterreciprocates.

A yielding presser I-I bears upon the upper surface of the goods ormaterial at or near the point where the cutter enters and automaticallyadjusts itself to varying heights of material. This presser is useful inpreventing the upper layer from being lifted out of place by thecutting-blade upon its upper movement, and it also operates to holdcertain grades of goods together with light pressure while the cutter isacting. It preferably has a rounded under surface h and a forked end 71,to span the cutter and foot-arm. It is preferably mounted or formed uponthe end of a long arm 7L3, pivoted at 77, to an arm which extendsforward from the frame of the machine, and this long arm so pivotedprovides the presser with a large range of vertical movement in orderthat it may accommodate itself to varying heights of the material to beout. It is moved downward and held depressed by the spring 7L5, attachedat one end to a sta- The blade tionary holder and at the other end tothe pivot h, which connects the link h with an arm h of a handle 7r, thehandle being thus connected with the presser, and it is located near themain handle I, by which the machine is grasped and moved.

I prefer that the presser-arm h be pivoted in front of the presser, asby so doing the presser is drawn over the upper layer and has a lesstendency to rumple it.

The handle I is formed bya portion of the housing which incloses thecross-head and supports the rods upon which it is moved, and it isdirectly over the cutter-that is, in the same vertical linetherewith-and I consider that this is a very favorable point from whichto direct and guide the machine, because it is near the point at whichthe cut is being made, and because it is in line with the cutter, andalso because it enables the operator to take a position where he canreadily see the marked line upon which the cutter is to be moved and ata point close to the cutting edge of the cutter.

The front section J of the housing is in the form of a removablecover-plate which covers the rods, cross-head, and upper part of theblade, and is secured to the remainder of the housing by screws to beeasily detached- It has formed in it a holej, with which the screwsecuring the blade to the cross-head may be brought into line, andthrough which it may be unscrewed and the blade removed for grindingwithout removing the plate. The blade is represented as having in itsupper end or shank a recess c and as having also the straight edges a bywhich it is made to fit the recess a in the cross-head. A fasteningscrewe passing through the recess into the cross-head, locks the blade to it.This recess permits the blade to be adjusted on the crosshead as itslower edge is ground off, and. to prevent it being forced upward Iemploy an adjustable backing or stop plate 6 having a slot 6 and teethback, which fit into the cross serrations or teeth e on the cross-head.These serrations serve to hold the stop-plate as against the verticalthrust of "the knife and the screw serves to fasten it to thecross-head.

The bevel-gear d has formed integral with it the counterbalanced, and itis arranged, preferably, between the bevel-gear d and the cross-head, asthis economizes space and permits it to carry the crank-pin 0Z renderinganother disk or separate crank-arm unnecessary. Its shaft (Z extendsfrom one side only and has a long bearing in the housing. (See Fig. 4c.)

To start and stop the cutter, a belt-shipper M is employed, which isarranged to move the driving-belt m from one pulley to the other,according as it is desired to start or stop the operation of the cutter,and this belt-shipper is adapted to be actuated from a point close tothe handle I, so that the op erator can by the same hand not only guideIIO or serrations 6 upon its the cutting-machine but may also start andstop the operation of the cutting-knife. This result is represented asobtained by mountin a sleeve m u on the housin to slide verticallythereon and providing it with an extension m toward the handle I to bewithin reach of the hand grasping the handle and in a position to beoperated by a downward.

movement of the hand upon said handle and to be held depressed by thehand while the machine is being moved by it. This sleeve is connectedwith the shipper by means of a collar 071 having an ear m to which issecured a rod m passing upward through a.

sleeve m to the end of the arm of the shipper. This sleeve m has aspring m which serves to hold when free the shipper in its highestposition and in engagement with the loose pulley to permit the shipperto be moved downwardly by the operator to engage the belt with the fastpulley and to automatically return the belt from the fast to the loosepulley when it is released by the operator, the operator holding downthe shipper in opposition to the stress of this spring to obtain theengagement of the belt with the fast pulley and the operation of thecutter.

I have represented the housing as made of the part A having anenlargement at its lower end and upon which the part A containing thebearing for the shaft d screws or is attached, and the part A providingthe handle and supporting the guides for the cross-head, which isscrewed or bolted to the section A The part A has screwed into its top asleeve A and the support A which secures the machine to the end of thearm, surrounds this sleeve and has conical recesses to fit the conicalupper end of the section A and the conical lower end of a nut or head aat the upper end of this sleeve. This support has a lateral hollowextension at, which screws upon the end of the said arm B, and

the sleeve supporting the shipper may act as a pin for looking it to theend of the arm after it has been so screwed by passing through holes inthis lateral extension and coinciding holes in the end of the arm. (SeeFig. 5.) I

The range of movement of the presser-foot is limited by the pin h on thehandle 7L9 and the sides h of the recess in the handle with which itcomes into contact. The pressure with which the presser bears upon thematerial is adjusted by connecting its spring h with the arm. h by meansof an adjustable plate 71 having a slot h through which a locking screwpasses and which plate is adapted to be moved upon the arm to vary thetension of the spring.

In use the cloth or other material to be cut is assembled in any desirednumber of thicknesses upon the bed or table 0, the upper one havingmarked upon it the lines upon which the layers are to becut. The machineis then moved to the beginning of a line and its foot arranged to extendunder the lowest layer.

The presser-foot which has been held elevated is released toautomatically close upon the upper surface of the pile. The operatorholds and guides the machine with one hand by means of the handle I, thehand being so placed as to also control by the belt-shipper theoperation of the cutter, andhaving started the cutter he moves themachine, which is practically entirely supported at the end of the armB, upon the line desired, the cutter reciprocating very rapidly andsevering the material by straight cuts, beginning at the top and endingin a shearing cut in connection with the shear cutter at the bottom, thefoot lifting the material upon the line of the cut slightly and inadvance of the cuttingpoint of the cutting devices as the machine ismoved, the presser-foot holding the upper layers from being disarrangedby the act-ion of the knife and the vertical arm of the foot alsospreading and holding spread the material upon the line of the out. timethe action of the cutter maybe instantly stopped by releasing itsstartmotion, the releasing mechanism being constantly under the controlof the operator as it travels with the machine.

A machine of this character has great capacity in respect to the numberof thicknesses it may cut and also in respect to the quality of thematerial out. It is guided with facilityand has great rangein respect tocutting curves and irregular lines, and it cuts the lowermost layers asperfectly as the uppermost.

It is desirable that the blade E be made thin upon its back from thefront edge a backward, or as represented at 6 Fig. 14, and also that thearm F be made thin from its front edge f, or as represented at f Fig.14.

It is also desirable that the entire back face F of the arm F bestraight and that the back face f of the foot be straight, exceptingwhere hollow and made out of line to form the shear cutter. By thusshaping these parts they may be moved in the cut fabric with lessfriction upon the sides, and they also serve to cause the pressure ofthe cut sides to assist in maintaining the reciprocating cutter incontact with the surface f of the arm F and also its cutting edge incontact with the edge of the shear cutter. This effect is also increasedby the point-forming bevel e and by the slightly-inclined relation ofthe blade of the cutter E to the arm F, the said shaping and arrangementof parts tending to assist in maintaining the contact between the At anydesired.

lower corner of the cutter and the back side the arm B by a two-armedconnection B the upper arm I) being pivoted to the support at the outerend of the arm 13 in a manner to permit of a slight movement of the endof the arm 13 upon a vertical are, and the lower arm I) being connectedwith said support by means of the slot B therein, which spans a block Z2and with which block the arm I) has a forward and back yieldingadjustment by means of a bearing block or piece 17 carried by the arm 6and held in contact with the block b by means of a spring cutter,

b the tension of which 1s regulated by the adj usting-screw Z), thespring 19 and block 19 being carried in a horizontal hole .in the arm Bythis construction the cu tting-machine is floated, as it were, upon thecompressed spring 11 and the extent of its buoyancy may be varied byvarying the tension of the spring.

It is desirable that the foot and its holding arm be located in front ofthe reciprocating as shown, as they then act additionally as a guard inprotecting the fingers or the hand of the operator, it being customaryto ascertain at times the location of the foot under the goods by hand.

It is understood that this invention may be used for cuttingmaterial ofany kind and whetherarranged in layers or not. It is not intended thatthe use of the words cloth or fabric shall have a limiting effect. 1

I consider the type of foot which I have described as the best, but donot intend to limit the invention to a foot of the shape specified, asit may be of a different shape and may have a portion upon the otherside of the cutting devices, and the bottom of the foot may not beentirely straight and it may not bear continuously upon the bed. Thestroke of the reciprocating blade may be varied to the number ofthicknesses which it is desired to out, and where that number is smallits reciprocation might well be decreased, provided, of course, themachine is used exclusively for that or a less number of thicknesses.

It will be noticed that the cutting instrumentality is of a compositecharacter, in that it combines two different principles of cutting, theplunger or reciprocating blade first acting unaided to cut a portion ofthe assembled layers by a plunging cut or dab and then acting to outwith a shearing cut, the upper cutter being converted into a shearcutter and being combined with a stationary shear cutter and continuingthe cutting of the material therewith, not as a plunger cutter, but asone cutter of a pair of scissors engages the other that is, with theshearing cut of scissors-blades. The device varies from scissors inconstruction, however, in that the lower shear-blade is alwaysstationary and the upper reciprocating or plunging blade does not,during the scissors part of the out, have a swinging movement on apivot, but a direct movement toward the stationary shear cutter upon avertical line, each partof the cutting edge having the same extent ofmovement and being impelled by the same force. The power which maintainsthe front face of the cuttingblade near its lower rear corner in contactwith the guiding-surface of the vertical arm during its plunging actionalso maintains its be established and maintained while the said cuttingedge of the plunger cutter is passing by the cutting edge of the shearcutter.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States 1.
